SAND-BAG cons'rnuc'rron Application filed June 21, 1927. Serial No. 200,438.

This invention relates to a sand bag construction and has for its primary object the design of a sand bag having a self-contained heating device so arranged as to subject the contents of the bag to the maximum heating effect.

An object of the invention is the incorporation in a sand bag construction of a steam heated device arranged to be partly sub- 1 merged in the sand contents of the bag in the use of the latter, thereby subjecting the sand contents to a maximum amount of heat continuously, thereby assuring the sand bag being at the proper temperature at all times to accomplish satisfactory results.

Another object of the invention is the novel manner of constructing the sand bag of detachable units to materially reduce the cost of manufacture and the cost of assemblage.

Besides the above, my invention is distinguished in the construction of a sand bag incorporating a steam coil through which steam is constantly passed for subjecting the bag to a uniform continuous heating action, thereby keeping the sand bag at a uniform temperature which has a decided advantage in the pressing of a felt hat as they must be subject to a uniform heating action during the entire period of pressing.

A feature of the invention is the novel manner of constructing and arranging the companion casings, so that when they are slipped into engagement with each other and bolted together a rigid support is provided 85 for the sand bag proper, while at the same time a steam chamber is provided for receiving and confining steam in the proper position to subject the bag to a maximum heating efl'ect. 7

With these and other objects in view, the invention will be better understood from the following detailed description taken in connection with the accompanying drawings wherein:

' Figure 1 is a top plan view of the sand bag construction, a

Figure 2 is a side elevation, Figure 3 is a sectional view on line 33 of Figure 1,

Figure 4 is a sectional view on line H of Figure 3,

Figure 5 is a sectional view on line 55 of Figure 1, 7

Figures 6 and 7 are detailed cross sectional views of corner portions of the structure, and

Figure 8 is a cross sectional view through a modified form of the invention.

Again referring to the drawings illustrating one of the many constructions of my invention and more particular to Figures 1 to 7 inclusive, the numeral 1 designates the supporting structure to which is attached the compressing device 2 of a flexible construction and preferably designed in the form of a sand bag similar to those now on the mar ket. The supporting structure 1 in this particular design of my invention consists of an outer casing 3 and inner casing 4, the latter removably mounted within the former and spaced therefrom to provide a steam chamber 5. There are various ways in which the the casings can be detachably secured together to provide the steam chamber 5 and to facilitate assembling thereof, but for the purpose of illustration, I have shown the outer casing 3 provided with an exterior flange 6, secured to the flange 7 of the inner casing by means of the bolts 8. A gasket ring 9 is arranged between the flanges to provide a steam tight joint. The inner casing 4 is further provided with an interior flange 10 directly bolted to the top 11 of the outer casing by means of the bolts 12. Associated with the flange 10 is a gasket ring 13 to pro vide a steam tight connection. An insulating lining 14 covers the inner surface of the outer casing and a similar lining 15 covers the under surface of the top 11 so as to insulate the outer casing against the rapid dissipation of the heat created by the steam confined within the chamber 5 and the heat emanating from the steam coil 16 paralleling the lining 15 and arranged to heat the compartment 17 provided within the inner casing for accommodating the travel of the compressing device.

The coil 16 is removably held in place by the strips 18 that cross each other at an angle ably secured to any suitable support.

and engage the under surface of the coil with their ends directly secured to the casings by the bolts 19.

The compressing device in this particular case consists of a sand bag 20 that has its marginal edge portion 21 passed over the flange 6 and clamped in place by the clamp ring 22 that is contracted about the outer surface of the outer casing by the thumb bolt 23. p

To complete the invention I have provided a bracket 24 illustrated as a spider having its limbs 25 directly secured to the outer surface of the outer casing. This bracket is provided with a head 26 projecting upwardly from the bracket and adapted to be deli-212i n inlet pipe 27 communicates with inlet end of the coil 16 and an outlet pipe 28 communicates with the steam chamber 5 so that live steam can be continuously passed through the coil and through the steam chamber for keeping theinterior of thedevice at a constant temperature.

In Figure 8 I-have'illustrated a single casing 29 having insulating lining 30 with which is associated a steam coil 31, certain convolutions 32 of which paralleling the top of the casing while other convolutions 33 are arranged in spaced parallel relation with the-side of the casing so'that thesand contents of the device will be subject to the maximum heating effect facilitated by the arrangement of the side convolutions certain of which are embedded in the sand when the sand is forced into the compartment 34 during the pressing operation. Supporting strips 35 are sodesigned as to effectively embrace the convolutions to hold the same in place but are capable of quick detachment through the utilization of the screws 36 that engage the strip and the flange 37 of the casing.

A filling opening 37 is provided in the outer casings for allowing the sand or other granulated material to be passed into the bag and this opening 37 is adapted to be closed by a perforated gate 38 'slidably mounted in the guides 39 and manipulated by the finger piece 40, Thus the opening 37 is capable of performing a dual function of allowing material to be passed into the device and to establish a restricted communication between the interior of thedevice and the atmosphere so as to accomplish the proper heating of the interior of thestructure.

which causes the sand contents .to travel into the compartment provided within'the casing where the sand will be subject to an additional heating action by certain of the coils by the heating device submerged within the sand contents. Thus it will be understood that the sand contents is directly subject to a heating action by the contacting engagement of the sand particles with the heating device and indirectly by the transmission of heat through the space of the compartment, and as the heating effect is continuous it will be appreciated that the sand contents is kept at a uniform temperature at all times.

Due to the construction and relative arrangement of the parts, it will be understood that the various casings may be formed by stamping operations and may be quickly assembled by placing one casing within the other and securing the same by a relatively few bolts. The sand bag can then be quickly connected to the supporting structure by means of the clamping ring after which the sand contents may be poured through the filling opening 37 to completely fill the bag and partially fill the compartment provided with in the casing. The steam in passing through inlet 27 traverses the coil and steam chamber for subjecting the structure to the proper heating effect, and as this steam is'caused to travel continuously, it will be appreciated that the temperature of the device may be raised to any desired degree.

In the particularconstruction of my invention, illustrated in the present application, the various casings may be formed by a stamping operation and the various coils may be effectively secured in place by detachable supporting brackets, but I wish it to be understood that the supporting structure may be constructed in various other manners than illustrated and various other suitable heating devices may be utilized for'heating the interior of the device and besides various other types of compressing devices may be suspended from the supporting structure and,

therefore, I do not desire to be limited in protection in any manner, whatsoever, exceptas set forth in the following claims;

What I claim is:

1. A sand bag construction comprising a casing having-an open :bottom, a sand bag secured to and enclosing the open bottom of said casing and a steam coil arranged in the casing and having certain convolutions embedded in the sand of said bag.

2. A sand bag construction comprising a casing having anopen bottom, a-sand bag secured to and enclosing the open bottom of said casing and a steam coil arranged in the casing and having certain convolutions embeddedin the sand of said bag and brackets having an abutting relation with said coil. and directly attached to said casing. I

In testimony'whe'reof I aiiix my signature.
